$184 mistake you’re making when you go overseas

We all know the routine. We arrive home from an overseas holiday with a wad of foreign notes and a pocketful of useless coins and stash them in a drawer.

We always think we'll save them for "the next trip" - but we know deep down, that cash will probably never see the light of day again.

It's hard to avoid coming home from a holiday abroad without extra foreign currency - whether in the form of notes and coins, or stored on a travel money card - that many of us don't worry much about it.

But it's an expensive conundrum. According to research by finder.com.au, the average Aussie holiday-maker comes home with $184 worth of foreign money they're likely to waste. You could fly from Sydney to Brisbane and back again with that.

Australian men come home with $205 worth of unspent foreign currency and women return with $164, according to a finder.com.au survey of more than 2000 Aussie travellers.

So it's definitely worth getting it out of the drawer and putting it to better use, finder.com.au's money expert Bessie Hassan said.

"Australians should dig out their spare holiday cash because it could be worth more than they realise," she said.

"It's very common for people to think it's too much hassle to exchange leftover foreign currency and don't bother converting it back to Australian dollars.

"I would advise anyone with a stockpile of foreign notes and coins lying around at home to explore what it might be worth."

OK, so what do you do about it?

The first thing to remember is currency exchange services don't generally accept foreign coins (and notes have to be in good condition) - so you have to get rid of those coins.

Do you know there are donation boxes at airports all over the world that collect your spare foreign coins and donate them to worthy charities? You probably don't - according to finder.com.au's research, less than 5 per cent of Australian travellers actually use them.

Airlines also accept leftover change on board and donate them to good causes.

"If you're already back in Australia and want to use leftover foreign cash to support a charity, you can donate it to charity like UNICEF," Ms Hassan said.

Airports and airlines are happy to accept leftover holiday money, which they donate to worthy causes.

"For instance, at any Bankwest branch, 100 per cent of the donated funds go to UNICEF's Coins for Kids program, which helps provide essential resources to children in need."

Notes are worth converting to Australian dollars, and many currency exchange services in Australia - as well as some banks - will buy back your holiday money.

"Look at the 'buy' exchange rates as this will help you lock in the most competitive rate when converting the currency back into Australian dollars. The service may also be offered through your bank, but make sure you check the costs associated with doing this as will vary depending on the provider."

Ms Hassan said hotels and airports were the worst place to exchange your currency.

"While it's more likely that you'd exchange foreign currency at a hotel or airport in a foreign destination, it's still important to remember to avoid this once you've touched down on home soil," she said.

"Using the wholesale exchange rate, available online, means that both of you will usually get a better deal than if you went to a currency exchange service," Ms Hassan said.

Increasingly, though, our leftover holiday money is stored electronically on travel money cards. Those travellers come home with even more unspent foreign currency ($267 each, on average) than those relying on cash.

Of course they can easily transfer this money back into Australian dollars, but the exchange rates are likely to be higher.

Finder.com.au advises funds transferred to your card will be subject to the currency conversion fee on the day, which are often similar to credit card conversion rates.

"As a general tip, don't transfer more cash into a foreign currency on your card than you expect to use," Ms Hassan said.
"Often, you'll lose money by converting to an international currency and converting back again."
